active color contact lenses

Abstract

A pair of active cosmetic contact lenses endows more natural appearance to the pupils of a cosmetic contact lens user, enables the colors of the pupils to show different texture in different scenes according to the relations of the irises of different users and comprises stacked composite structures and electrically-connected leads located among annular whole-ring substrate layers, wherein each stacked composite structure comprises multiple annular whole-ring substrate layers formed by cutting wafers, the annular whole-ring substrate layers have an electrochromic function, each stacked composite structure surrounds the periphery of a central optical area, and the annular whole-ring substrate layers attach to insulation layers. The pair of active cosmetic contact lenses is characterized in that the annular whole-ring substrate layers are connected through the electrically-connected leads in parallel, each substrate layer is in serial connection one transparent resistor, resistance values are gradually increased from inside to outside to enable the electrochromic strength of the substrate layers close to the central optical areas to be lower during lightening, each substrate layer is provided with same or different microstructures distributed in a dotted mode, and the adjacent substrate layers are similar or same in light color.

Description

[0001] The present invention relates to an active beauty contact lens with a plurality of stacked electrochromic functions. Background technique [0002] The market share of contact lenses is increasing. With the improvement of people's living standards, contact lenses are not only used for vision correction, but also endowed with the effect of a color contact lens, and are more and more favored by beauty lovers. [0003] Of course, eye wearers prefer natural-looking color contact lenses, so contact lens designers around the world are working hard on various designs in terms of color and shape of the coloring structure. When considering the shape, it is usually necessary to consider its oxygen permeability, permeability and other issues. Therefore, it does not mean that the expected goal can be achieved after a well-designed shape. Sometimes after the design is completed, it can only be worn in a real environment. Considering the iris conditions of various wearers, it is very ...

When considering the shape, it is usually necessary to consider its oxygen permeability, permeability and other issues. Therefore, it does not mean that the expected goal can be achieved after a well-designed shape. Sometimes, after the design is completed, only through wearing it in a real environment, Considering the iris conditions of various wearers, it is very difficult to determine whether the design is successful after repeated experiments
